The winch encoder 3, it can be used for obtaining the pulse signal related to travelling block heave amplitude.
Due in acquisition process, easily being disturbed by other signals, cause dry doped with other in the pulse signal
Signal is disturbed, if directly may result in single-chip microcomputer 5 to single-chip microcomputer 5 by the data information transfer that winch encoder 3 obtains and obtain mistake
Pulse signal, so as to cause the judgement of mistake by mistake.
, can be by the signal processor 4 that is connected with the winch encoder 3, to institute in the utility model embodiment
State pulse signal and carry out anti-interference process.
The process of anti-interference process can regard as extracted from interference signal it is related to travelling block heave amplitude
The process of pulse signal.
When winch works, the drilling line twined on roller can be utilized, steel wire rope is existed by the rotating of control shaft
Rope woolding or rope is put on roller, the purpose of to realize the raising of travelling block or decentralization.
In the utility model embodiment, signal processor 4 can be according to the judging phase order winch of the pulse signal
Rotation direction, so as to judge the increase and reduction of the rise and fall of travelling block, i.e. heave amplitude value.Single-chip microcomputer 5 with it is described

The change of angle value, corresponding voltage analog is produced, and subtracted using voltage analog control winch electromagnetic brake device
Speed.
The moderating process of winch electromagnetic brake device can realize the control to travelling block heave amplitude value, but due to
The moderating process of winch electromagnetic brake device is relatively slow, it is possible that occurring heave amplitude value more than preset upper limit
After value, continue the situation of increase, or heave amplitude value less than the situation for after preset lower limit value, continuing to reduce.For this kind
Situation, single-chip microcomputer 5 can be according to the second preparatory conditions pre-set, by controlling Pneumatic brake device of winch promptly to be stopped
Car.
Next the concrete condition for meeting heave amplitude value the second preparatory condition is deployed to introduce.It is directed to travelling block

Cheng Zhong, if the heave amplitude value of travelling block is more than or equal to the spacing value of highest either when the heave amplitude value of travelling block is small
When minimum place value, emergency brake can be carried out by Pneumatic brake device of winch, so as to prevent travelling block from emitting
Crashing into the crown.
Specifically, when the second monitoring unit in single-chip microcomputer 5, monitor that heave amplitude value is more than or equal to the spacing value of highest
Either when heave amplitude value is less than or equal to minimum place value, then the pneumatic control output unit is triggered, output is pneumatic
Control signal, so as to control Pneumatic brake device of winch to brake.
